Explanation:
There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.
In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.
Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.
Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.
Answer:
At the end of 6 hours, 6 feet of the ladder remained above water
Explanation:
we are given the following:
change in tide = 8 inches per hour
1 hour = 8 inches
∴ 6 hours = 8 × 6 = 48 inches
Now, since the length of the ladder is measured in foot, let us convert the rate of tide rising to foot.
12 inches = 1 foot
dividing both sides by 12:

Therefore, after 6 hours, the tide rises by 2 feet.
Next, we are told that the rope ladder at the beginning was 8 feet, hence the length remaining above water after 6 hours of the rising of the tide is calculated as follows:
= 8 feet above water
height of tide = 2 feet = amount submerged in water
∴ length above water = (ladder before rising of the tide) - (amount submerged in water)
length above water = 8 - 2 = 6 feet
Therefore at the end of 6 hours, 6 feet of the ladder remained above water
Answer:
Many animals and plants regenerate tissues or even whole organs after injury. Typically, specialized cells at the wound site revert to a 'pluripotent' state–via a process called dedifferentiation—which means they regain the ability to develop into the various cell types required for regeneration.

Anna does not need to get a sample in every box.
The process of sampling involves taking out a representative quantity of the whole in order to study the properties of the whole.
The sample taken for study must reflect the properties of the whole. It must be taken in such a way that all parts of the whole are represented.
Recall that Anna had six recipes from which she made 30 boxes; five boxes of caramel bar of each recipe.
She may collect two caramel bars at random from any of the five boxes containing a particular recipe.
This means that Anna will have a total of 12 caramel bars for sampling.
